What kind of velocities can you get with the Dasher/75 Vmax combo. The rifle is a LRPV with a 26" 12 twist barrel. I am looking for a good 3-600yd PDog load. Hoping for 3500fps or so.

I have a 23" long 8-twist 6mm Dasher that I have been shooting the 75-grain V-Max bullets with IMR 8208XBR powder. My sweet spot as I call it, very tight groups with single digit stand deviations is 3300fps, I have ran it up to 3400fps without any signs of pressure however, my groups and SD started to increase.
So with that being said, 3500fps plus with a 26" barrel shouldn't be a problem.

I'm getting 3345 FPS with the 70 GR. Nosler BT using IMR 8208 XBR with single digit SD in a 22" barrel. That combination in a 10" twist is very accurate in my standard 6mm BR. I would thing the Dasher should do much better.
Just to give you another indication of what to expect.
